I basically am looking for terminals where I am supposed to connect the required VCC and GND on this Glow Plug When I check the continuity using the multimeter,it comes out as a single unit. Does that mean that the glow plug is dead?

A glow plug is essentially an intentional short circuit that heats up a wire and ignites whatever fuel is in or connected to the glow plug.

Polarity rarely matters in this. But typically, the construction has the larger body as "ground" and the center pin as "vcc". There is an isolation ring that protects the two from each other, so current goes through the wire.
